SUMMARY

The discussion centers on calculating the average force exerted by a puck on a hockey goalie. Given a puck mass of 0.15 kg traveling at a velocity of +59 m/s, and a catch time of 0.0021 seconds, the average force calculated is 4214.029 N. Participants confirm the calculation's accuracy and emphasize the importance of showing the work behind the answer for clarity and learning purposes.

PREREQUISITES
  • Understanding of Newton's second law of motion
  • Basic knowledge of momentum and impulse
  • Familiarity with significant figures in scientific calculations
  • Ability to perform calculations involving mass, velocity, and time
NEXT STEPS
  • Study Newton's second law of motion in detail
  • Learn about impulse and momentum calculations
  • Review significant figures and rounding rules in physics
  • Practice similar problems involving force calculations in sports contexts
USEFUL FOR

Physics students, sports scientists, and anyone interested in the mechanics of sports dynamics will benefit from this discussion.

A hockey goalie m=85kg stands in front of the net. A player hits the 0.15kg puck towards the goalie with a velocity of +59m/s. The goalie catches the puck with his glove in a time of 0.0021seconds. (assume all collisions are linear)

A) what is the average force of the puck on the goalie?

I got the answer to be 4214.029N is this correct
 
Physics news on Phys.org
Yes, that's correct. Two comments:
(1) Round off to a reasonable number of significant digits.
(2) To get the best help in the quickest time, never just give an answer, always show how you got the answer.
 
Alright sorry about that and thanks a lot I appreciate the advice
